How can the
strength of light be measured?- the effect on degradable materials

Introduction

Light has some benefits and some hazards.
In tunnels and roads, sufficient light offers a safer driving condition,
while low light creates hazards and accidents. Photographers need to
measure the amount of light in order to adjust their camera and produce
a clear picture.

Project
description
In this project you will study light measurement and the effect of light
on degradable material. You may purchase a light meter or by spending
about $20 you can build your own light meter as a part of your project.
